ROLL FOR LEATHER-WORKING MACHINES.

SPECIFICATION forming part of Letters Patent No. 344,069, dated June 22,1886.

Application filed April 5, 1886. Serial No. 197,889. (No model.)

To all whom it may concern:

Be it known that I, J osnrn W. VAUGHN, of Peabody, in the county ofEssex, State of Massachusetts, have invented a certain new and usefulImprovement in Rollers, of which the following is a descriptionsufficiently full, clear, and exact to enable any person skilled in theart or science to which said invention appertains to make and use thesame, reference being had to the accompanying drawings, forming part ofthis specification, in which- Figure l is a side elevation of myimprovedroller, and Fig. 2 a diagram showing the arrangement of the flanges.

Like letters of refererce indicate corresponding parts in the differentfigures of the drawings.

My invention relates to that class of rollers which are employed inmachines for puttingout, striking-out, fleshing, scouring, and unhairinghides and skins in the manufacture of leather; and it consists in thenovel construction and arrangement of parts hereinafter fully set forthand claimed, the object being to produce a more effective and desirablearticle of this character than is now in ordinary use.

The nature and operation of the improvement will be readily understoodby all conversant with such matters from the following explanation.

In the drawings, W represents the body of the roller, and x w thejournals, the body being preferably composed of Wood, and provided'witha band or hoop, e, at either end. The roller is provided peripherallywith aseries of main flanges, 45, arranged in rows, which start from acircumferential line at 48, and pass spirally around the body of theroller outwardly to either end, as shown in Fig.

1. The main flanges 45 are respectively provided at uniform distancesapart on their sides or faces with short auxiliary flanges 46, which arepreferably slightly curved and stand at an angle of about forty-flvedegrees to the bodies of the main flanges. The auxiliary flanges may beformed integral with the main flanges, or made separately, as desired.The ends of the flanges 45 overlap each other, spaces 47 being leftbetween the overlapped ends to form channels, through which the waterexpressed from the hide or skin may flow, there by enabling the water tofind its way to the ground more readily than it would. if said flanges45 were united to form a continuous flange, this feature being ofespecial advantage in treating very wet hides and skins. The rows offlanges being also composed of short flanges or sections, aremoreconvenient andless expensive to construct. The short or auxiliaryflanges 46 are of the same height as the main flanges 45, but do notextend entirely across the spaces between the rows which are formed bythe flanges 45, thus leaving a space, 49, between the rear ends of theshort flanges and the front faces of the main flanges, which serves as achannel to assist in carrying off the water expressed from the hide orskin, and causing it to drop to the ground. The edges of the flanges maybe angular or rounded in any degree, or in accordance with the work theyare required to perform, and when rounded may be safely applied to thegrain side of the hide or skin. The long or main flanges 45 remove thelight fleshings from the hide or skin and stretch it downward,and alsodiagonally outward, while at the same time the short or auxiliaryflanges 46, which stand nearer to a right angle with the longitudinalaxial line of the roller than the flanges 45,

stretch it laterally or more nearly in a line parallel with said axialline. When constructed with angular edges, the flanges readily removethe lighter fleshy parts of the hide or skin; but they may be soconstructed as to render the machine adapted to green-shave or removethe heavy or thick fleshings, if desired. As the the flanges 45 of theroller all start from a common circumferential line, 48, the hide orskin at the part corresponding therewith would not be properly put outor treated if the flanges 45 only were used, or if the short flanges 46on the line 48 were arranged in regular order, and therefore the shortflanges at that point are irregularly arranged, as shown. The shoulderportions of a hide or skin are usually somewhat baggy or full, and inorder to perform the work properly it should be put out or stretched ineither direction from the shoulders. The line 48, or starting-point ofthe flanges 4.5, is therefore placed a short distance to the left of thecenter of the roller, in order to bring it over the shoulders of thehide or skin and enable that portion to be properly put out or treated.The starting-point of the flanges or line 48 may, however, be located atthe center of the roller to the right of the center, if desired. Byoverlapping the ends of the flanges 45 said flanges are causedtostanda't 'ajdifferent angle with respect to the longitudinal axialline of the roller than they would stand at if arranged end to end or ina continuous line, thereby producing somewhat better results than would1 be attained by arranging them as last described, and also formingchannels 47 for carrying off the water. Idonot, however, 'confine myselfto overlapping the ends ofythe. flanges 45, as they 'may be arranged endto end or in a continuous line and perform their functionssatisfactorily; neither vdo I confijne myself to leaving the spaces 4?between the end'sof said flanges when they'areoverlapped, i as they maybebVerlapped and the ends iefti in contact, or approximatelyf'so, andthereby greatly-increase their efficiency whether the, spaces 47 areleft between'theo'verlappedendsj or not; neither do I confine myself to*tliei use of any special'number of 'auxiliaryflanges on the main"flanges, "as one or m'oie may be: employed.

Having thus'e'xpla'in d my invention, wha't ,7 v we Z 1. In a roller ofthe"character'described{the body Wflprov'ided peripherally with 'aseries of main flanges, 45, "having one or more auxiliary flanges, 46,said main flanges being arranged in rows which start at or near thecenter of said body and extend spirally around the same outwardly toeither end thereof, substantially as described.

2. A roller having a series of peripherallydisposed scraping or cuttingflanges arranged in rows which pass spirally around or partially aroundthe body thereof, certain of said rows starting at a circumferentialline orpoint which is located between a line drawn transversely throughthe cent-er of said roll and one of its ends, substantially as shown anddescribed.

3. In a roller of the character described,the

main flanges 45, having one or more auxiliary flanges, 46, said mainflanges being arranged in rows which start at or near the center of theroller, and pass spirally around the. body thereof, and have their endsoverlapped, substahtially as described. I

'4. Inaroller of the character described, the main flanges 45, havingone or more auxiliary flanges, 46, said main flanges being arranged inrows which start ator near the center of the rollera'n'd pass spirallyaround the body thereof, said main flanges having their ends overlappedand separated to form the channels 47, substantially as set forth.
